What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Phoibos Leviathan

Owners widely report the Phoibos Leviathan offers a vintage experience at an affordable price due to its proportions and conservative design. However, the watch is considered well-made and sturdy but quite heavy, with a 45mm x 54mm lug-to-lug case and a 15.5mm thickness, leading some owners to replace the stock band. On balance, owners rate the Phoibos Leviathan highly for its vintage feel and sturdy build at its price point.

From video reviewers

The watch features 500m water resistance and a Seiko NH35 automatic movement. The case size is a point of contention, with reviewers noting it is substantial and may overwhelm smaller wrists, while others highlight a 40mm case size as an improvement.

Seiko Essentials Quartz

Seiko Essentials Quartz owners praise its high quality and value, highlighting its thin 8.4mm case, sapphire crystal, 100m water resistance, and quartz convenience, with the titanium variant weighing just 50g for exceptional comfort. The polished surfaces can develop fine swirls from daily wear, and the gold plating may wear off edges over time, requiring maintenance. The titanium bracelet's smaller center link creates wider gaps than the steel version, and some owners prefer to remove the 50m-rated watch for showering, especially if it lacks a screw-down crown. On balance, owners rate the Seiko Essentials Quartz highly for its comfortable, lightweight titanium build and convenient quartz accuracy at the price.
